My driving season ended rather early and abruptly last year when my F/I TR7 suddenly died after taking a turn, and had to get flatbedded home. Being a F/I TR7, the electric fuel pump wasn't working. The pump was some after market one, and the air flow meter had been jumpered so that the pump energized all the time the ignition switch was on (not to OEM specs). So...no power to the pump. Spent a couple hours checking things out...inertia switch...check. Combined relay...check. Fuel pump...dead. Well, a short time after that my dad passed away, and I kind of lost my ambition to work on it, so she's been up on jackstands in the garage all winter.
Fast forward about 5 months. Weather's getting nice, so figured it's time to see if I could track things down. Checked the inertia switch again...check. Power coming off it...check... but only when cranking (hmmmm, the Air Flow meter had been jumpered and so should have power anytime the ignition was on). Pump dead. So...I had a used OEM pump, so decided to just swap it in. Still dead when just in the on position. Then I turn key, and wala...she starts and runs! That was the good news. The bad news was the used pump has a serious leak, so had to shut her down. Ordered a new pump yesterday.
So...all of a sudden the electrics (that had been modified by a PO) started working the way they are supposed to, but only with an OEM pump. Very strange...but happy I was able to trace it down without having to tow her to a shop.
